Graphty

Android Library to display graphs

Installation

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Step 2. Add the dependency

Add the following dependency in your app build.gradle:

implementation 'com.github.valerybodak:Graphty:1.0.7'

Usage

1. WeekLineGraph

1.1 Put WeekLineGraph to your xml layout

<com.vbodak.graphtylib.graph.week.WeekLineGraph
    android:id="@+id/weekLineGraph"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

1.2 Setup WeekLineGraph and display it

val params = WeekLineGraphParams()
    params.minValue = 0
    params.maxValue = 950
    params.valueScaleWidthPx = 82F
    params.titleTextSize = 30F
    params.weekdayStart = Calendar.SUNDAY
    params.weekdayNameMap = mapOf(
        Calendar.SUNDAY to "S",
        Calendar.MONDAY to "M",
        Calendar.TUESDAY to "T",
        Calendar.WEDNESDAY to "W",
        Calendar.THURSDAY to "T",
        Calendar.FRIDAY to "F",
        Calendar.SATURDAY to "S"
    )

binding.weekGraph.setup(
    params = params
)

...

binding.weekGraph.draw(
    values = listOf<Int>(32, 176, 33, 568, 7, 65, 43)
)

2. BarGraph

2.1 Put BarGraph to your xml layout

    android:id="@+id/barGraph"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

2.2 Setup BarGraph and display it

val params = BarGraphParams()
    params.minValue = 5
    params.maxValue = 100
    params.valueScaleWidthPx = 82F
    params.titleTextSize = 30F
    params.barColors = listOf(R.color.cyan, R.color.pink, R.color.yellow)
    params.barCornerRadiusPx = 6F

binding.barGraph.setup(
    params = params
)

...

binding.barGraph.draw(
    bars = listOf(
        Bar(title = "12/10", values = listOf(80, 10, 98)),
        Bar(title = "13/10", values = listOf(65, 87, 76)),
        Bar(title = "14/10", values = listOf(69, 32, 15)),
        Bar(title = "15/10", values = listOf(46, 15, 23)),
